The outerface of theguard member 12 is preferably flat to form a seat for'the razorblade 14 which is preferably clamped be-' tween a shoulder 15 on a screw threaded stud 16 on an outer clamping cap 1'5" and the outer end of an enlarged portion 18' on a rod 19" slidable in the hollow stem 11 and normally spring-pressed by a spring 20 seated on anin-y terior shoulder on the-stem 11 and against a" shoulder on a manipulative portion 21 secured to-the rod 19 by a rivet or the like, asshownf The enlarged portion 18 is screwthre'a'ded interiorly to cooperate with the re 5 duced threaded end of the stud 16 on the cap member 17 by means of which the razorblade 14 may be clamped between the shoulder '15- onthe clamping cap 17 and the end of the enlarged portion 18 of the rod 19 by a clockwise turning movement of the manipulative member 21 and rod 19. Likewise, the blade 14- may be removed from the clamping cap rod 19'by turning the manipulative means- 21 counterclockwise;- The side edges of the" clamping cap hold'th'e edges of the razor blade against the face of the guard member in the usual manner. i a

By means of the construction described, the razor blade 14 will be held in positionon the guard member 12 but may be raised away fromthe guard member 12 by pressure on the manipulative member 21 for the purpose of disengagin alining studs 22 on the clamp ing cap 17 from alining holes in the guard member l2,after which the razor blade may be turned aboutan axis passing through the rod 19 by turning the manipulative portion 21 so as'to present either edge oftheblade in cooperative relation with the guard fingers, or with the sharpening device which, in i the form shown, comp rises aroller 24.

The roller 24 is constructed of any suit-f able material and may be provided with a spiral :rib 25, as shown in Fig.7, or as pro-- This invention relates to improvements in combinedisafety razors and sharpening de- V1095;

.Among the objects of this invention is improved means for supporting a sharpening device in either of two positions on opposite faces of the edge of a safety razor blade in cooperative relation therewith, and improved m means facilitating moving said sharpening ff device and razor blade relatively from one cooperative position to the other.

Another object of this invention is the provision of a combination of means for facilitating the sharpening of either edge of a 1'5" double edged safety razor blade. 7

Still another object of the invention is an improved sharpening roller.

Other objects will be apparent from the following description taken in connection Fig. 1 is a side View of a combined safety razor and. sharpening device;

, N Fig. 6' is a central longitudinal section of re the razor head and carriage;

Fig. 7 is a section on the line 7-7 of Fig. 2; and

Fig. 8 is a perspective view form of sharpening device. 1

The safety razor may include a handle 10 of any preferred form which is secured to a of an improved in Fig. 8 inwhich it is designated26, and

ferred the roller may be .of the form showni hollow stem 11 integral with a guard member 12 which at one of its side edges carries guard fingers 13 of any suitable preferred '30 form .l i

which is provided, as shown, with spaced longitudinal extending ribs 27 which, when the blade springs into the grooves formed between the ribs when the roller is revolved,

studs 32 and 33 carried by flanges 34 and 35 on a carriage 36 which is provided with ears 37 and 38 in which the sharpening roller 24 or 26 is suitably journaled. "The flanges 34 and 35 are preferably of the shape indicated by reference characters a, b, c and d of which the edge Z) bears against the rear face of the guard member 12when the roller is in the position shown in Figs. 1, 2 and 3, to cooperate with the studs 32 and 33 to hold the roller in the position indicated in these fig-c ures. The sliding connection between the studs and the slots-in the ears 30 and 31 permits the roller to be moved in a plane parallel with the plane of the safety razor blade as the roller is drawn toward the right. It also permits the roller to be pivoted about the studs in a direction toward the face of the edge of the razor blade as pressure is applied in that direction. The slots in the ears 30 and 31 permit the roller to be moved from the position shown in Fig. 3 to the position shown in Fig. 4 prior to its being pivoted or rocked into alinement with the position it occupies in Fig. 5, and to permit its movement into the position indicated in Fig. 5. In this position the edges a of the flanges 34 and 35 bear against the rear face of the guard member 12 to hold the roller substantially in the position indicated. The relation of the edges a to the studs 32 and 33 is such as to permit the roller to be pressed against the upper face of the edge of the razor blade as pressure is applied during the operation of sharpening.

The carriage 36 may also be provided with flanges 39 and 40 which are of the general shape of the flanges 34 and 35 as indicated bythe reference characters 6, f, 71,, i and j, of which the edges f and h function the same as the edges 0; and Z) of flanges 34 and 35., As the carriage is moved to the right, as shown in Fig. 4, the cam edges of the notch g in the edges f of the flanges 39 and 40 coact with the wedge-shaped ends of the studs 22 to raise the razor blade and clamping cap 17 into the positionshown in Fig. 4. This compresses the spring 20, the reaction of which is to apply pressure on the edges h of the flanges 39 and 40 after the studs 32 and 33 have been moved into the position shown in Fig. 4. The result of this is to initiate the pivotal movement of the roller carriage from the position shown in Fig. 4 in an upward direction toward the position it finally assumes when in cooperative relation with the upper face of the edge of the razor blade, as shown in Fig. 5. From this position the carriage is moved to the left into the position shown in Fig. 5 in which honed or stropped by turning the roller 24 or 26 after which the parts are manipulated so as to bring the roller into the position shown inFigs. 1, 2 and 3 which position they occupy during shaving operations.

As indicated in Figs. 1 and 3, the studs 22 prevent any appreciable movement of the carriage to the right so that the roller will remain in substantially the position shown unless. it is drawn to the right. The studs also hold-the roller substantially in the position shown in Fig. 5 unless force isapplied to draw it'to the right.

Then the roller is in the position shown in Figs. 1, 2 and 3, and it is desired to reverse the position of the edges of the razor blade, pressure is applied on the manipulative portion 21 on the rod 19 to raise the razorblade until alining pins or studs 22 are free ofthe guard member 12, after which a rotational movement of the razor blade is effected by turning the manipulative portion 21. After this has been effected the spring 20 is permitted to drawthe razor blade into the position shown in these figures.

lVhile the invention has been described with reference to a preferred form'of mounting means for the sharpening device and with reference to preferred forms of sharpening means, it is to be understood that changes may be made withoutdeparting from the spirit ofthe invention and the claims are not to be limited by the terms of the description therein employed only to the extent that they are limited by the prior art.
